280 FLOEA OF LOWER COAL MEASURES OF MISSOURI. 



species, are, iu general, to be found onl)" in the higher coals of the anthra- 

 cite series. Thus, from a cursory glance at the stratigraphic range of the 

 species giA'en on the high authoritj^ of Professor Lesquereux iu the above 

 list, it appears that most of the plants of limited range are more or less 

 distinctly peculiar to the coals below the Freeport in the Ijituminous fields 

 of Pennsylvania or the Mammoth vein in the region of the Southern Anthra- 

 cite field iu the same State. 



The second list of the fossil plants of the Carbonifei'ous of Missouri is 

 that embodied in Mr. G. Hambach's Preliminary Catalogue of the Fossils 

 Occurring in Missouri.^ In this enumeration we find, besides the species 

 listed by Lesquereux, a number of others, as follows: 



Neuropteris tenidfoUa Brongn., 



Spheiiopteris cristata Stb., 



Lepidophyllum majus Brongu., and 



Taonurus CoUetti Lx. from Henry County. 



INetiropteris fimbriata Lx. and 



Desmiopyhlhtm gracile Lx. from Jasper County. 



LepUlodendron aculeatum Stb. from Yeiiiou County. 



Trigonocarpus Daicesii L. and H. and 



T. olivcvforniis L. and H. from Cedar County. 



Since there is no statement to the contrary, we may infer that these 

 additional species are recorded on the basis of identifications made by Dr. 

 Hambach. 



If we consider these species frona the standpoint of their affinities and 

 stratigraphic occurrence, we may note that Neuropteris temiifolia as a name 

 is somewhat ambiguous in this country, some of the material, even con- 

 tiguous fragments, included tliereunder being identical with other material 

 known as N. Loschii. The species, in an}'' case, is unknown to me from 

 below the Lower Coal Measures, though it ascends probably as high as the 

 Lower Barren series (XIV) of the Pennsylvanian sections. Neuropteris 

 fimhriata Lx. is not found until we reach some distance above the base of 

 the Coal Measures, and it passes up into the higher coals of the Northern 

 Anthracite field. Desmiophyllmn gracile is \evj close to Tmiiophyllum lati- 

 folium. Lepidodendron aculeatum Stb. should have a Avide range in the 

 upper part of the Lower Coal Measures, while Trigonocarx>us Batvesii, if
